Dr. Animo

Aloysius James Animo, later known as the D'Void, is one of Ben Tennyson's enemies, a mad scientist obsessed with genetic experiments on animals.

Dr Animo has the power to telepathically or empathically control animals. This includes ordinary animals, but also his mutant monsters and even aliens, as he was able to take control of the Null Guardians. According to the enhanced version of Secret of the Omnitrix, he learned this power from one of Ben's other enemies, Clancy, who could control bugs and other arthropods the same way. How and when he met Clancy is a mystery.

In addition to this power, Animo is a genius and brilliant scientist, skilled in both machines and genetic experiments, who usually uses his knowledge to give him additional powers. His trademark invention, the Trans-modulator and its variants (including on two occasions a device he called a De-Evolution Bomb), allows him to turn animals into powerful, dangerous mutants who serve as his minions. His other inventions include a machine able to convert heat into energy used to increase his strength and durability (Voided) and a head band amplifying his control over animals so he could control creatures like Yeti.

In addition, Animo is - partly out of necessity - a master of technical improvisation capable of constructing his devices from the simplest of materials. The prototype of his Trans-modulator was constructed from commercially available electronic components and an alternated kitchen sieve.

In the original series, he usually relied on armies of animals mutants to fight for him.
